You walk nervously down the street. It is eerily quiet. It seems you didn’t get the memo that tonight is not the night to be out and about. Suddenly you see a figure out of the corner of your eye. Not really wanting to find out what it is, you walk a little faster. A second later, the figure is in front of you, still in the shadows of the street when he addresses you. “Good evening. I apologize for the experience you are about to have, but it seems you are the only one still out.”
